Air compressors and superchargers belong to a class of compressors, which can compress the gas and increase the pressure of the gas. The air is processed by the compressor and can be used in various fields, such as industrial gas filling, oxygen production, food packaging, refrigerator refrigeration, etc. However, due to their different working principles and use occasions, there are significant differences between air compressors and superchargers.
First of all, from the working principle, the air compressor is a compressor that works in accordance with the principle of positive pressure, mainly pressurizing the surrounding air for storage. In popular terms, it is to compress a large amount of air into a small volume of material through mechanical equipment in order to facilitate storage, transportation and use. Air compressors have a variety of classification methods, such as from the air compression ratio can be divided into low pressure compressors and high pressure compressors; From the type of gas can be divided into dry press and oil lubricated compressor. Different types of air compressors have their own characteristics and scope of application.
In contrast, the supercharger is a compressor that works according to the principle of negative pressure, using a high-speed rotating impeller or the principle of centrifugal compression to pressurize the gas. Superchargers are usually used in high-speed fans, turbochargers, ultrasonic sprayers, aerodynamic control and other fields. Compared with the air compressor, the processing advantage of the supercharger is that it is particularly suitable for compressed air, that is, it can compress the gas into a gas with a certain flow rate or velocity, and has a more specialized application scenario.

Secondly, from the point of use, air compressors are usually used in manufacturing, metallurgy, automobile repair, chemical and other fields. For example, circuit board equipment in the manufacturing industry must use gas to clean and dry, which requires a large amount of air source, and air compressors can provide the required air source. In the field of metallurgy, air compressors are also widely used in blast furnace gas pressure and steel casting. Superchargers are more widely used in industrial automation, gas transmission and testing. For example, superchargers can be used to pressurize hydrogen cylinders, supply gas to electrical equipment, increase the pressure of compressed air, and so on.
Finally, from the perspective of compression ratio, there are also essential differences between air compressors and superchargers. The compression ratio of air compressors is usually within the range of 10 to 20, and the compression ratio of superchargers can reach more than 30 times. It can be said that the supercharger has higher compression capacity than the air compressor. In addition, the air compressor usually requires the outlet air pressure and temperature to be relatively stable, while the supercharger has high adjustability and can be adjusted according to the needs of different occasions.
In summary, although air compressors and superchargers belong to a class of compressors, there are significant differences in their use occasions, working principles, compression ratios and so on. If you want to compare the two, from the compression ratio, the application of the situation, the supercharger has a greater advantage.
